Welcome to our 2008 Electrical and Computer Engineering newsletter. We hope this newsletter will keep you, a member of our extended ECE family, informed

about what is happening in the ECE department since you've gone out and made a career.

Currently, the ECE department has over 400 undergraduate students, over 40 gradu-ate students (M.S. and Ph.D.), 17 faculty and offers two majors (Electrical and Com-puter Engineering) making it one of the 50th largest ECE department in the nation. Our department offers specialization in biomedical, computer, controls, communication and signal processing, electronics, electromagnetics, power, and optics. Our Department offers Bachelor degree programs in Electrical Engineering and Computer Engineering. We offer M.S. and Ph.D. programs in Electrical and Computer Engineering. Last year we graduated 75 B.S., 7 M.S. and 1 Ph.D. degrees. Our enrollment is increasing, we now have 486 students, making us the larg-est department in the College.

In this issue you'll get the details on a number of exciting new developments such as new faculty hired, awards by faculty members and students, research grants,

various student projects, and publishing activity by our faculty. This year we are piloting a new commercialization process coined Bison Ventures. This process takes the best student/faculty ideas and provides funding and a pathway to establish new companies. Next year, we hope we can tell you about some successes in this process.

As you read this newsletter you'll realize these are but a few of the accomplishments of members of our ECE Department. As a continuing service to our alums we offer video recordings of our seminar series on-line for your perusal. We're continually upgrading our website with new recordings so check http://134.129.123.46/vsts.htm often.

Dr. Robert Nelson has returned to his home state of Wisconsin full-time at the University of Wisconsin-Stout to help establish a new engineering program. We all miss him, especially whenever the Minnesota Vikings beat the Green bay packers. We’ve missed him a lot this year!

Finally, we offer our best wishes for you in the new year and cordially invite you to email, phone or stop by when in the vicinity and tell us what's happening to you in your career. We want you to feel a part of the ECE family.

2008-2009 ECE SCHOLARSHIP RECIPIENTS AND AWARDS

Ashley Bakken was an electrical engineering student at NDSU, Fargo. He left the program in 2006 so that he could work full-time and complete the apprenticeship hours he needed to ob-tain his journeyman electrician’s license. He would have earned his master’s license, with the resultant pay increase and ability to reduce his work hours, this February, and was plan-ning to return to college full-time in September 2008 to com-plete his electrical engineering degree. Tragically, he was killed in a motor vehicle accident on November 24, 2007.

Ashley’s family has established a scholarship fund in his mem-ory specifically for electrical engineering students. Recipients of this scholarship will be required to be NDSU, College of Engineering and Architecture students enrolled in Electrical and Computer Engineering. Preference will go to those candi-dates who have previously completed an electrical related pro-gram, i.e. and Associates Degree in Construction Electricity, or will hold the position of an Apprentice, Journeyman, or Master Electrician, and demonstrate financial need.

HAILS AND FAREWELLS


Long time professor Cap Collins passed away May 11, 2008. He began his 31-year teaching career at NDSU (then NDSAC) in 1958, Cap was a devoted instructor whose door was always open to students needing extra help, at all hours of the day or night, and devoted to his profes-sion. Over the years Cap held many state, local, national offices with the

National Society of Professional Engineers and was named North Dakota “Engineer of the Year” in 1975.

Cap was very active in the Kiwanis, serving pancake breakfasts for 45 years, and put in countless volunteer hours with the Boy Scouts of Fargo. Chairing the Chamber of Commerce’s energy committee, Cap organized Fargo’s fly-over rooftop heat-loss survey in 1973, one of the first in the Midwest, and many other civic and local energy education and conservation pro-

grams. He also wrote and produced a weekly editorial com-mentary program on KDSU, the University’s radio station, covering history, politics, and scientific and current events topics.

Cap took special pride in his service on the North Dakota Grasslands Commission, dealing with land reclamation in the surface coal operation of Western North Dakota, which com-bined his passion for preserving the environment with his engi-neering and mining experience.

Cap served on the first Review Board created under the North Dakota’s automobile “lemon law” in 1979, and for decades as faculty advisor to Tau Beta Pi, the Engineering Honorary Soci-ety at NDSU. Granted professor emeritus status at NDSU, Cap continued with the department, administering EIT and state accreditation programs, and teaching part-time until his last class, in 1989, at the age of 79.

CAP COLLINS, LONG TIME EE PROFESSOR PASSES AWAY

After being at NDSU for a total of 23 years, some might say that the ‘pull’ of Packer country became too powerful for Dr. Nelson and his wife to overcome! : ) Well – that is not quite what happened.

While it is true that Dr. Nelson and his wife Mary recently moved from NDSU to Menomonie, Wisconsin – it was NOT because of a football team! The University of Wisconsin – Stout recently received approval from the Wisconsin Board of Regents to offer Computer Engineering in its Department of Engineering and Technology. Dr. Nelson was invited to join the staff at UW-Stout to help build and develop this program. Talk about a tough decision!!

The Nelson’s have thoroughly enjoyed their years in Fargo, and Dr. Nelson maintains that the ECE Department at NDSU is one of the best places that he could possibly work. How-ever, in the end the opportunity to move closer to all of their family members (Dr. Nelson and his wife are both from Wis-consin) while helping ‘birth’ a new engineering program in their home area weighted very heavily. As a result the Nel-son’s moved in August from Fargo to Menomonie, Wisconsin.

For those unfamiliar with Menomonie, it is a great place to

come for a visit (Hint-Hint : ). Menomonie is about 60 miles east of St. Paul – right on I-94. The University (University of Wisconsin - Stout) is a bit smaller than NDSU (enrollment of 8700), and is part of the University of Wisconsin system.

With the approval of Computer Engineering, Stout is the first UW-school north of Madison (i.e., the only one in the central or northern part of the state) to have either Electrical or Com-puter Engineering.

The Nelson’s express their warmest appreciation to all who made their many years in Fargo so pleasant. In particular, thank you to all the ECE students, faculty and staff. You have made NDSU a great place to be! You are all most welcome to come and visit anytime.

Dr. Nelson’s new contact information is: Dr. Robert (Bob) Nelson, Professor and Computer Engineering Program Direc-tor, Engineering and Technology Department, 332 Fryklund Hall, University of Wisconsin—Stout, Menomonie, WI 54751. Office phone: 715-232-1984. E-mail address: [email protected].

NEWS FROM THE FACULTY

Members: Munir Kaderbhai, Pushpanjali Prasad, Pulkit Mal-hotra, Jameson Bickert, David Harris, Ryan Sullivan, Trevor Hauck, Eric Hagen, S. Yuvarajan (Advisor)

Fall 2008 scholar team on Renewable Energy has eight mem-bers from graduate level to sophomore, all very enthusiastic in learning all about solar power and applying to automobiles. Even though cold, North Dakota has many sunny days. This justifies research on solar power. The following are the activi-ties taking place:

Solar powered battery charging and running of interior heater fan combo: In this project, a solar panel by the windshield pro-vides power to charge the vehicle battery or an auxiliary bat-tery and this keeps the batteries warm and fully charged in winter weather. This helps to avoid starting problems in cold weather for cars parked outside in the parking lot. A timer is used to divert the solar power to run a heater fan combo shortly before the vehicle is driven off from the parking lot.

1. During summer, the solar panel charges the auxiliary bat-tery that can run the same fan to cool the vehicle interior. All

this comes without wasting gas.

2. Power Electronic Converter for Solar Panel: A switching converter converts the voltage from the solar panel to match the battery or to run a fan at different speeds. This will help to control the charging rate for the battery and fan operation in (1).

3. Driveway Lighting: A small solar panel is used to turn on the light in the driveway when the car enters the driveway in the night. An SCR/TRIAC circuit is triggered by the headlight and the driveway light stays on until it is manually turned off.

4. Remote Control for Car: Transmitter-receiver ICs are used to design a remote control for turning on/off the loads in a vehicle. The team members learn to use low-cost ICs in transmitting and receiving data through an encoder/decoder combination.

NELSON AND ULVEN RECEIVE TEACHER, RESEARCHER OF THE YEAR AWARDS

There are currently 23 senior design projects, eight of which are Design III projects that were recently demonstrated at the Senior Design Demo Day. Of the eight completed projects, three were industry sponsored projects. These included a touchpad testing device (Daktronics), a vending machine monitoring system (Appolis), and a linear acceleration com-pensated tilt sensor (Appareo).

Two of the completed Design III projects were power-related projects. These projects consisted of a rotor controller for a doubly-fed induction gen-erator and a fuel-cell powered DC motor con-troller. Another project that consisted primarily of developing software was image encryption using new pseudo random

number generation systems. This project was developed in the Matlab environment and it investigated the creation of cipher-text from images and ciphers. The security level of the cipher was then tested against chosen-plaintext attacks (CPA).

Two other pro-jects consisted of receiving and displaying broadcast sig-nals. One in-volved receiving radar images from Polar Or-biting Environ-mental Satellites (POES), performing signal conditioning in hardware, processing the signal on a digital signal processor (DSP) chip, and displaying the image on a graphic display. The other project involved development and optimization of open-source GNU Radio software to demodulate an ATSC HDTV signal acquired through a Universal Software Radio Peripheral(USRP). The software was written in C++ and Python.

The Design II class currently has 15 projects. One system be-ing developed is a wireless communication system intended for motorcycle use. The project was proposed by engineering student Andrew Ellenson. Ellenson is being provided with a team of students, an advisor, and funding to develop his pro-ject idea. His proposal was in response to an invention and entrepreneurism-building opportunity provided to the design class.

Some of the other Design II projects include the development of a telephar-macy work-station, a mi-croprocessor, a unique ex-ercise device, a device to test integrated circuit chips, an en-ergy harvesting system, an educational Rube Goldberg-style system, and two Bobcat sponsored projects.

A welcome addition to the design course is a new cir-cuit board milling ma-chine. This machine will allow for the

development of complex, detailed circuit boards with 1 mil traces. Gone are the days of the light box and chemical etching of boards.

You can access more detailed information on the projects men-tioned here at the department’s wiki site located at: http://saturn.ece.ndsu.nodak.edu/ecewiki/index.php/ECE_Senior_Design_Groups.

The ECE department encourages individuals and compa-nies to spon-sor student design pro-jects. Spon-sorship is $3,000 per two-semester project and is a great way to develop a closer relationship with the ECE department and graduating students, provide skill-set development for stu-dents, obtain preliminary designs and prototypes, and help support student design activities within the department. If you would like to sponsor a project or have questions, please can contact Prof. Mark Schroeder at (701) 231-8049 or [email protected].

During these eight months, Dr. Green completed 350 pages of the book. Added to the 100 pages previously completed, the book is now two-thirds com-plete at 450 pages. With Dr. Green teaching three courses

during the fall semester of 2008, including signals and systems, random processes, and applied digital signal processing, a somewhat delayed completion of the book is anticipated in late spring or early summer of 2009.

DAVID ROGERS This year Dr. David A. Rogers has served as advisor for one master’s student, joint advisor with Dr. Robert Nelson of two Ph.D. students, and interim advisor for two other Ph.D. students. He also served on the thesis committees of two students who completed there M.S. degrees this year (Cherish Bauer Reich and Dustin Vaelaar). He advised two senior design teams working in the area of RF design. This fall he was a joint author of the paper “Developing a CAD Tool for Radio Frequency and Microwave Engineering Edu-cation” presented at the American Society for Engineering Education (ASEE) North-Midwest Section Meeting at the University of Wisconsin at Platteville. Master’s student Divya Bais was the principal author of this paper.

Nationally Rogers served as a reviewer for the Proceedings of the 2008 ASEE Annual Conference, Pittsburgh, PA, June 2008 and the Proceedings of the 2008 ASEE/IEEE Frontiers in Educa-tion Conference, Sarasota Springs, NY, October 2008. He also was a reviewer and member of the Editorial Board of the International Journal of Microwave and Optical Technology.

Locally he was member of the NDSU faculty committee that revised the promotion and tenure policies of the University.

He also served on NDSU commit-tees for local selection of candidates for the Goldwater Scholarship and for the Jack Kent Cooke Memorial Scholarship. He chaired the ECE Promotion, Tenure, and Evaluation Committee and served on the Col-lege of Engineering and Architec-ture Promotion, Tenure, and Evaluation Committee as ECE De-partment representative. He is also a member of the ECE Department Faculty Search Committee.

Rogers is a Life Member of the IEEE and the ASEE. He is also a member of the Applied Computational Electromagnet-ics Society and the Atmospheric Science Division of the American Geophysical Union. He is registered as a profes-sional engineer in the State of Washington.

In the community Rogers is an active participant in the Fargo-Moorhead Brazilian Connection and serves the Red River Radio Amateurs as a volunteer instructor and as a volunteer license examiner.

NDSU and Dickinson State University have joined forces for a new engineering program. The two universities signed a memorandum of understanding Aug. 18 in Dickinson to pro-vide a collaborative curriculum in computer, electrical, indus-trial and manufacturing engineering.

After successful completion of two years of a structured cur-riculum at DSU, students will transfer to NDSU so they can complete the NDSU bachelor’s degree.

“This will have a profound impact on the engineering and manufacturing sectors of our state’s economy,” said NDSU President Joseph A. Chapman. “We expect this agreement to help meet the increased need for engineers in the western part of North Dakota, where manufacturing has taken a resounding leap forward. It allows Dickinson area students to remain close to home for two years as they prepare to complete their de-grees at NDSU.”

To help facilitate the engineering collaboration through in-creased relationships with local industrial and manufacturing companies, NDSU also will have Extension engineers in Dick-inson, Bismarck and Minot.

According to President Chapman, the agreement is similar in design to the successful collaboration in agriculture the univer-sities have enjoyed since 2000. “DSU has been a great partner in agriculture and we look forward to more success with the

engineering agreement,” Chapman said. “This agreement adds to the strength of the North Dakota University System, and is a wonderful example of how the eastern and western parts of our state can work together to achieve lasting success for all of us.”

All students admitted to DSU and declaring one of the four engineering majors will pay the NDSU engineering program fee. Students enrolled in DSU courses will pay DSU tuition, while those taking NDSU courses will pay NDSU tuition. NDSU will review and approve all core curriculum course offerings in the cooperative program, ensuring that courses taught at DSU are equivalent in content and structure to the courses taught at NDSU.

The agreement was signed by President Chapman; Richard McCallum, DSU president; Craig Schnell, NDSU provost and vice president for academic affairs; and Rich Brauhn, DSU vice president for academic affairs.

Rajesh Kavasseri, associate professor and graduate coordinator in the Department of Electrical and Computer Engineering, has been awarded a grant of $75,357 from the National Science Foundation’s Division of Electrical, Communications and Cyber Systems. He will use the grant to research static voltage stability in bulk electric power systems using Grobner basis techniques.

According to Kavasseri, the phenomenon of voltage stability has been identified as a significant threat to power system security and reliability. The project, in addition to advancing knowledge and understanding in the area of GB reduction techniques for multiple power flow solutions, would also provide a theoretical foundation to facilitate analytical (static) voltage stability studies in larger power systems. The proposed algebraic-geometric tech-niques can be applied to obtain analytical and theoretical insights in networks arising from other contexts, for example, wireless communication and sensor networks. “If successful, the effort will contribute to improved security and reliability of one of the na-tion’s most critical infrastructures, the electric power grid,” as stated in his award abstract. The educational plan is to absorb the

proposed research techniques into a graduate course in power systems analysis at NDSU.

Kavasseri earned his bachelor’s degree at Visvesvaraya Regional College of Engineering at Nag-pur, India; his master’s degree at the Indian Institute of Science at Bangalore, India; and his doctor-ate from Washington State Uni-versity at Pullman, Wash. His research interests are focused on the dynamics, stability and con-trol of electric power systems. Contact Kavasseri at 1-7614 or [email protected] for more information.


KAVASSERI RECEIVES AWARD FROM NATIONAL SCIENCE FOUNDATION


Prestige, money and a summer of rigorous work are the re-wards that five gifted NDSU students earned through academic excellence and the North Dakota Space Grant Program.

Two NDSU students received prestigious research fellowships through the NASA Space Center Summer Internship Program. In addition, three students received summer research positions at NDSU through the new Space on the Prairie Summer Re-search Fellowship Program. Both programs are funded by the NDSGC using federal and state dollars.

Through the federally-funded internship program, Peter Barfknecht, a senior majoring in mechani-cal engineering from Embarrass, Minn., and Aaron Fisk, a senior majoring in me-chanical engineering from Langdon, N.D., are studying and conducting re-search at NASA facilities this summer. Each received a $6,000 fellowship and round trip transportation expenses.

Barfknecht is working at the Goddard Space Flight Center, Greenbelt, Md., while Fisk is at the Jet Propulsion Labora-tory, Pasadena, Calif.

“They are working with NASA’s top-of-the-line people,” explained Suezette Bieri, deputy director of the program, noting Barfknecht and Fisk were in com-petition for the internships with students from across the country. “These summer internships allow them to make contacts with very important people in NASA.”

Barfknecht’s summer project involves research and develop-ment of the Constellation-X satellite, which is an X-ray tele-scope that will peer into deep space to investigate supernovae, super-massive black holes and distant galaxies.

“I am proud to represent NDSU here at Goddard Space Flight Center,” Barfknecht said. “It is truly a unique experience to work with some of the brightest scientists and engineers on some of the most advanced scientific projects in aerospace.”

According to Barfknecht, he is facing many challenges in his work. “X-rays are very difficult to focus since they are ab-sorbed by or pass through most materials. A special type of mirror is required to reflect the X-ray photons. The rays must skim the surface at a very shallow angle,” he said. “Also, the mirrors must be extremely thin and smooth to within a few microns. The telescope will use several hundred of these ar-ranged in concentric shells. The challenge is to produce, align and mount the mirrors without distorting them out of focus.”

Fisk, meantime, is working on development and testing of fiber-reinforced composite materials with enhanced material properties at the JPL Materials Testing Lab. “Receiving the acceptance letter for a summer internship position was an as-tonishing honor,” he said. “It is a great opportunity for stu-dents from North Dakota, or anywhere, to be given this pres-tigious honor and experience.”

Bieri said three other NDSU students received full-time re-search opportunities through the state-funded Space on the Prairie Summer Research Fellowship Program. They are Nic-

cole Schaible, a graduate student in elec-trical and computer engineering from Mott, N.D.; Curtis Engelhart, a senior majoring in chemistry from Bismarck; and Cody Satterlee, a senior majoring in elec-trical engineering from Williston.

Each student received $6,000 for the fel-lowships. This is the first year for the pro-gram, and if successful, the program is expected to expand in the future.

Schaible and Satterlee are working in the cardiovascular laboratory of Daniel Ewert, professor and chair of electrical and computer engineering. Engelhart is working in the laboratory of Mukund Sibi, NDSU distinguished professor of chemistry and molecular biology.

“Our North Dakota students, with their intelligence, creativity and work ethic, can compete with stu-dents anywhere in the United States,” Bieri said. “These stu-dents are outstanding, and it is exciting to see the valuable work they are doing is in line with the vision of NASA.”

According to the consortium’s Web site, North Dakota first received a Space Grant College Capability Enhancement Grant from NASA in 1990. The North Dakota Space Grant Program is headquartered at the Department of Space Studies at the John D. Odegard School of Aerospace Sciences at the Univer-sity of North Dakota. The program’s mission is to make the education and research infrastructure in North Dakota more NASA-relevant.

DRINK ‘ASSISTANT’ ALLOWS INDEPENDENCE Associated Pres Published Sunday, December 30, 2007 DICKINSON, N.D. – Dickinson High School sophomore Mitch Hintz is like any other high school student. He likes to hang out with friends, he thinks about career options, and he had a wish list for Christmas.

One item on his list is unique – he wanted to take a sip of water without the assistance of anyone.

Mitch, the son of Mike and Donalda Hintz, was born with cerebral palsy, damage to the part of the brain controlling movement. Areas of the brain that define a person’s intelligence are not affected.

“His dream was toa be independent and able to take a drink without asking someone all the time,” Donalda Hintz said.

His dream came to the attention of Dickinson High School Special Services Department Chairman Elaine Lindemann and family and consumer science teacher Mary Bruhschwein.

“Mitch has limited use of his hands. He can’t hold on to a glass. You have to hold it for him,” Lindemann said.

“I met Mitch in the hallway. He has such a fun sense of humor. He told me his goal was to get a drink of water on his own,” Bruhschwein said. “I was trying all kinds of things I could do on my own, and nothing worked.”

Last year, Bruhschwein met an engineer during a chance encounter in a Valley City, N.D., flower shop. Through him, her request came to the attention of a North Dakota State University electrical engi-neering professor.

“We did a long conversation about Mitch. I could submit a proposal, but he couldn’t promise anybody would take it,” she said.

NDSU students Adam Lawler of Linton, Nathan Livingston of Minot and Sachin Garg of India accepted the challenge of designing a drink assistant as their senior project.

“We’re all electrical engineers. We’re all seniors,” Lawler said.

The students wrote a report outlining their conceptual design, budget and timeline in February. Funding for the project came from a National Science Foundation grant.

“The basic plan was to start with a drink-aid system. Basically, it’s a bottle and mounting bracket with flex tubing,” Lawler said. “We attached a pump system on it. You don’t have to use suction. The water is delivered to you.”

He said the main challenge was to make sure the product was safe.

“We spent a lot of time working on different plastics that would fit for this project. We decided to introduce a cleaning system. Also, we made sure the plastics were strong and durable so they wouldn’t corrode with the cleaning systems,” he said.

A microprocessing chip runs the cleaning system. The program is controlled by buttons found on front of the enclosure.

“It’s a relatively simple program that’s on there,” he said. “We de-

signed the pump system and cleaning system to operate on separate circuits.”

Lawler said the power source is the two 12-volt batteries that oper-ate the wheelchair.

“It draws a few micro amps of power. It draws up to 8 amps when the pump is being primed. After that, the pump when activated only draws 2½ amps. Those few micro amps will have very little effect on the battery throughout the day,” he said.

Another challenge was to create a plastic mouthpiece that would withstand a biting muscle spasm. Livingston contacted a plastics company in Minot. The company designed two mouthpieces.

The students also made sure the device was small, portable and could easily disconnect from the wheelchair.

The design calls for two relays in the circuitry. When the mouth-piece sensor trips a relay, 1.5 ounces of water are pumped into the mouth and then shuts off, regardless if the tube is still in the mouth or not. The system only resets if the mouthpiece is exposed to light again. Another relay prevents the pump from turning on if Mitch goes into a dark room.

“We were pretty confident going into it when we first started. Some of the circuitry Nathan already used before. He was really confident going into the design stage,” Lawler said. “My part of the design was the power system. I was pretty confident it would work as well. The part we weren’t sure about from early on was the cleaning system. It required quite a bit of time and work.”

In their final report, the students said the electronics should require no replacements as long as the device is used as intended for at least 10,000 cycles, based on the expected life of the mechanical relays used to operate the pump.

After the device was tested and approved, the students made a trip to Dickinson to deliver the drinking assistant to Mitch.

He took his first drink of water and told them: “It’s cool! Thanks a lot.”

His teachers and parents share in the excitement and gratitude to-ward the NDSU students.

His mother, Donalda Hintz, said the drink assistant might also be used in nursing homes.

“It’s very awesome. It’s making Mitch independent. He needs help eating and dressing, but this is something he can do for him-self. You should see the smile on his face,” she said.

“He’s happy,” she said. “It’s one of the best presents ever.”

RFID CATTLE TAGS Project Director: Douglas Freeman; ECE Faculty: Jacob Glower

Both CNSE and ECE faculty and staff are developing a high-frequency RFID system for animal tracking. This system will develop an UHF RFID tag and data man-agement system to 1) track calves and cull cows from ranches in ND through the

feeding and processing steps at facilities in KS, addressing mar-ket enhancement objectives of animal ID. This involves col-laborations with the College of Vet Med at KSU; and 2) track cattle in collaboration with the College of Vet Med at Michi-gan State University using the TB surveillance program as a real, field exercise addressing disease surveillance, disease con-tainment and animal ID.

Our engineering group has procured the recently released new generation of Alien Technology RFID readers to upgrade the field installation at the DREC ranch. These new readers are

smaller and provide improved performance. We have also procured a new system from Alien which has an integrated antenna and reader suitable for reading tags in the field in cases where multiple antennas are not required.

We are also characterizing the effects of weather on UHF RFID systens. A weather monitoring system which monitors the performance of a UHF RFID cattle tag is being developed. This will record the performance of such tags throughout the year in actual North Dakota weather and over time. This will provide us with long-term survival and performance data of the tags being developed at NDSU.

An NDSU delegation traveled to India for two weeks in De-cember to strengthen international partnerships.

President Joseph A. Chapman and his wife, Gale; Prakash Mathew, vice president for student affairs; and David Wit-trock, dean of the graduate school, were among the NDSU representatives to visit the Ansal Institue of Technology, which has a twinning agreement with NDSU. The Agreement allows students to study two years at each school and earn degrees from both institutions.

Chapman said NDSU is preparing students to succeed in a global economy. “We feel we have an obligation to North Dakota and the region to be a major player in globalization of this area,” he told the Forum of Fargo-Moorhead.

The group also visited Sri Lanka, where NDSU is developing collaborations. Wittrock said trips to Thailand and Korea are being planned to develop similar agreements.
